Specification of Letters Patent.

Patented Nov. 30, 1920.

Application led .Tune 16, 1919. lSerial No. 304,545.

To all whom t may concern.' y

Be it known that we, CHARLES E. ARCHER and EDWARD C. HUMPHREYS, citizens of the United States of America, residing at Detroit, county of` Vayne, State of Michigan, and Chicago, County of Cook, State of Illinois, respectively, have invented certain new and useful Improvements in Clutch or Locking Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings.

In our allowed application Serial No. 238,468, filed June 6, 1918, for certain new and useful improvementsA insignal lamps, there is disclosed a signaling device or lamp having a universal movement and which may be easily and quickly manipulated with one hand for signaling purposes, the lamp being applicable to airplanes and other craft'where it is necessary that a signal lamp be adjustable in all directions and capable of manipulation with vone hand,. so that `the aviator may also attend to. other duties while signaling. A novel locln'ng device is also disclosed for maintaining the lamp inanadjusted position, and this application is directed to certain improvements in the locking mechanism. The'present invention aims to provide a simple and compact clutch and locking device for shafts or rotary members relative to a support and the locking device will be hereinafter considered and then claimed.

Reference will now be had to the drawing, whereinl Figure 1 is a side .elevation of a signal lamp, partly' broken away and partly in longitudinal section, showing the lamp and its supporting yoke locked relative to a bearing; Fig. 2 is a longitudinal sectional view of Vthe locking device showing the same in position for simultaneously and its supporting yoke;

Fig. 3.3is a similar view showing the locking device in position for adjusting the lamp independent of its supporting yoke;

Fig. 4 is a cross sectional view taken line IV-IV of Fig. 1, and

Fig. 5'is a similar view taken on the line V-V of Fig. 1. Y

In the drawing, thereference numeral 1 denotes a support and clamped or otherwise connected'to said support is a tubular vbearadjusting the lamp on the ing 2 which has the outer end` thereof flanged, as at 3 to abut a yoke head 4 and said yoke head is rotatably held at the outerend of thetubular bearing by an annular member 5 connected to the yoke head and cooperating therewith in providing an annular groove for the flange of the tubular bearing, so that the yoke head may be rotated relative to the axis of said bearing. The hollow yoke head 4 has diametrically opposed hollow or tubular yoke arms 6 supporting casings 7 having trunnions 8 for a lamp 9.

Mounted on the inner end of the tubular bearing 2 is the hub 10 of a stationary toothed member 11 which has its inner face flush with the inner end of the tubular bearing.

Journaled in the tubular bearing 2 is a yoke sleeve 12 supporting the yoke head 4 and the inner end of the yoke sleeve 12 has a yoke toothed member 13 mounted thereon against the stationary toothed member 11, and provided with a hub portion 14 which extends to the inner end of the yoke sleeve 12.

Journaled in the yoke sleeve 12 is a lamp shaft 15 which has the outer end thereof eX tending into the hollow yoke head 4 and4 provided with a mechanism, generally designated 16, for transmitting motion to the trunnions 8 of the lamp 9, so that said lamp may be adjusted in the yoke and independently thereof. The lamp 9 may also be ad* j usted in synchronism with the yoke, and on the inner end of the yoke shaft 15 is mounted the hub portion 17 of a lamp toothed member 18 which incloses the hub 14 of the toothed member 13 and abuts said toothed member, all of the toothed members being of the same diameter. i

The manner of mounting the toothed members on their respective rotary bodies is best shown in Figs. 4.and 5, where it will be observed that the end of the yoke sleeve 12 has opposed facets or flat surfaces for the hub portion 14 of the toothed member 13, and the inner end of the lamp shaft 15 has similar facets or surfaces for the hub portion 17 of the toothed member V18. To prevent longitudinal displacement of Vthese members a nut or cap 19 is mounted on the extreme inner end of the lamp shaft 15.

Slidably mounted on the hub portion 17 of the toothed member 18 is the inner re duced end 2O of a lock housing 21, said lock housing having a stationary toothed wall 22 and a movable toothed wall 23, said movable toothed wall 23 being in the form of a ring or band loosely mounted in the outer end of Y Ythe housing 21 and retained therein by a flange or peened edge 24 of said housing. The toothed portions of the walls`22 and 23 longitudinally aline so as to be shifted into and out of mesh or interlocking engagement with the toothed members 11,13 and 18. f

The inner reduced end 20 of the lock hous- V ing. 21 has suitable hand grip members 25 and said housing has a spring pressed detent 26, preferably in the form of a ball, adapted 3.0 engage in an annular groove 27 in the i hub portion' 17 of the toothed member 18,

said ,grooveand detent defining a neutral position ofthe locking device. The lock housing isplaced inposition-prior to placingY the nut 19 on the end of the lamp shaft 15,

'and' then vsaid nut will cooperate with the lamp toothedmember 18 in limiting the sliding movement of the lock housing relative to f the toothed members 11, 13, and 18.

As shownin Fig. 1, the locking device or thehonsing thereof is in a neutral position and itisimpossible for the lamp or itssupporting yoke to accidentally shift. Since the v toothed member 11 is stationary and meshes with the movable toothed wall 23 of f the lock housing 21, and the toothed -Inembers 13 and 18 mesh with the Vmovable and stationary toothedwallsof the housing, it iS impossible torotate the lock housing'with- Y .out-longitudinally shifting the same, and

Y @the yoke sleeve l2 as an axis.

the detent26 engaging inthe groove 2T will prevent Vaccidental shifting of said lock housing. Y

j' The' hand grips 25 permit of the lool; housing being shifted longitudinally of the toothed members, andasshown in Fig. 2,

Ythe `toothed wall 23 of .the lock housing 21 Y is held stationary by the stationary toothed wmember 11,'but since the wall 23 is movable J l,inV the llock`housing,fsaid lock housing may be rotated and by reason of its interlocking engagement with the toothed members 18 :and 18, a rotary movement may beimparted to the yoke sleeve. 12 and the lamp shaft 15.,

. in either direction. It is therefore possible to'adjust the yoke with the lamp .remainingV stationary therein, thelyoke rotating about As vclearly shown in Fig. 2 ride out of the groove 27 and the correct l Vvposition of the lock housing will vbe Vdefined by vcontacting with the toothed member 18. .A .reverse positionis. shown in F 1g. 3 where thelock housing hasbeen Vpulled inwardly to place the'movable toothed wall'23 in Vengageinent with the stationary toothed mem- Y ber 11 and the yoke toothed `member 13.V

lThe yoke', toothed member 15S-is thereforel llocked relative 'to the stationary toothed Ymember 11, but the lock housing may be roltated toy impartV movement to the lamp shaft -15 by reason y'of' the -housing being'inter- :locked with the .lamp toothed member 18.

lFrom .theL foregoing, 'it will be. observed the detent may said'sel'ective means and adapted for locking vsusceptible to such changes as fallwithin the scope of the appended claims. f
